In the newest issue of Women's Health U.K. which is causing quite the stir as it features the supermodel butt-naked on the cover! — Teigen opens up about her workout routine, her new cookbook and exactly when she and her Grammy-winning husband are going to have children.

"I'm waiting for things to slow down, but things don't seem to be slowing down, ever, so I think, 'Just have one and deal with it," she told the magazine. "I'd love to have an excuse to be bigger. People will know as soon as I'm pregnant because I'll stop drinking." (We'll be sure to keep an eye out for that!)

This isn't the first time the foodie is talking about her future family. Last fall, she revealed to Us Weekly that she looks forward to having kids, and wants a lot of them. "I want a huge family," Teigen said. "We want a lot of kids. When it happens, it happens. For us it's hard because he's on the road so much and I'm working. People think it happens so easily ... but the stars really have to align to have a baby and it is a little miracle so when it happens ... we will be so happy."
